Abstract:
Using seedlings growth of Festuca sinensis infected-endophyte (E〖SX（B〗〖〗+〖SX）〗) and uninfected-endophyte (E〖SX（B〗〖〗-〖SX）〗) as material，the effects of NaCl concentrations on seedling length，root length，seedling fresh weight and root fresh weight of Festuca sinensis were studied for providing theoretical basis for the effects of Epichlo endophyte infection on salt stress by germination method of Petri plates.The results showed that in E〖SX（B〗〖〗+〖SX）〗 seedlings salt concentrations ranged from 1.0 mmol/L to 8.0 mmol/L promoted significantly seedling length，root length and seedling fresh weight (P<0.05)，and salt concentrations between 1.0 mmol/L and 2.0 mmol/L increased significantly root fresh weight (P<0.05).In E〖SX（B〗〖〗-〖SX）〗 seedlings root length was increased under salt concentration ranging from 1.0 mmol/L to 2.0 mmol/L (P<0.05)，seedling fresh weight increased significantly under all salt concentration except 1.0 mmol/L NaCl (P<0.05)，and root length and fresh weight were significantly inhibited by 8.0 mmol/L NaCl (P<0.05).Compared with E〖SX（B〗〖〗-〖SX）〗 seedlings，E〖SX（B〗〖〗+〖SX）〗 ones had higher seedling fresh weight under control conditions，E〖SX（B〗〖〗+〖SX）〗 ones had higher root length and seedling fresh weight under all salt concentration (P<0.05)，E〖SX（B〗〖〗+〖SX）〗 ones had higher seedling length under salt concentration ranging from 1.0 mmol/L to 4.0 mmol/L (P<0.05)，and E〖SX（B〗〖〗+〖SX）〗 ones had higher root fresh weight under 2.0 mmol/L or 8.0 mmol/L NaCl (P<0.05).There were high positive correlation between seedling length and root length，and between seedling length and fresh weight，which were higher in E〖SX（B〗〖〗+〖SX）〗 seedlings.
